BE SAFE ! To save time, some installers neglect to install safety switches when putting a remote start system in your vehicle. THIS COULD BE A FATAL MISTAKE and the maker of your system definitely warns against this careless act. This kit provides the PIN switch for under the hood, which automatically stops a car from being remotely started when the hood is open. (For example, while checking your fluid level, if a child pressed your remote start button your engine could suddenly start, placing you in immediate danger.) Also included is an on/off toggle switch, to enable you to bypass your remote start system. (For example - if you gave your keys to a mechanic or parking lot attendant) The yellow/black warning label, meant to be placed under your hood, is also included, which will alert anyone working on your car to the presence of a remote start system
